POWER-TRANSMITTING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 663,895, dated December18, 19010.

Application filed April 26, 1900.

`fornia, have invented certain new and useful Improvements in PowerTransmitting Machinery; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appert-ains to lnake and use thesame.

The invention relates to power-transmittin g machinery.

The object of the invention is to provide mechanism for lowering orefrom mines located on mountain sides to crnshers or stamping-millslocated at a distance of, say, between fifty and two hundred feet lowerthan the mine and to make use of the power that is generated by thelowering of the ore to operate the crushers or stamping-mills.

The invention. is particularly applicable in localities where there isno water-supply at hand or in localities where there is a scarcity ofwood, the absence of either of which tends to make the cost of crushingores so great that operating such mines would he unprofitable. Again,there are localities rich in ores where it would be impossible totransport a boiler and other large machinery. My mechanism, however,being easily taken apart and set up, can be readily carried on the backsof pack-animals, and in that manner carried to otherwise inaccessibleplaces.

The invention consists in certain features of construction andcombination of parts, which will be hereinafter fully described andclaimed.

In the accompanying drawings, Figure 1 is a front elevation of my devicein operation. Fig. 2 is a side elevation of the same.

In the drawings the same reference characters'indicate the same parts ofthe invention.

1 denotes a platform supported by a frame or trestle-work 2 and locatedat the entrance of a mine in a mountain side. The framework extendsdownwardly to a distance of, say, from iifty to two hundred feet andrests upon a ledge.

3 denotes tracks laid upon the platform 1 and extending back into themine for the dump-cars to bring ore from the interior of the mine to thechutes 4 and 5 and 6 and 7,

into which the ore is dumped. The chutes conduct the ore to the buckets8 and 9 and 10 and 12, which deliver it into chutes 13, leading to thecrusher or mill. The buckets 8 and 9 and 10 and 12 are supported inpairs by sprocket-chains 14 and 15, running over large sprocket-wheels16 and 17, respectively mounted on short individual shafts 18 and 19,journaled in suitable bearings in the upper portion of the framework 2.

2O and 21 denote two sprocket-wheels of less diameter than the wheels 16and 17. These wheels are also mounted on the shafts 18 and 19,respectively, to rotate therewith and carry endless sprocket-chains 22and 23, extending to small sprocket-pinions 24 and 25, mounted on shortshafts 26 and 27, journaled in bearings on the lower portion of saidsupportingframework 2.

'28 and 29 denote two spur gear- Wheels mounted upon the shaft 26 oneither side of the sprocket-pinion 24,driven by the chain 22.

30 and 3l denote two spur gear-wheels mounted in like manner on theshaft 27, journaled in bearings on the opposite side of the framework 2.This shaft and gears are driven by the chain 23.

32 and 33 denote two shafts jonrnaled to directly beneath the shafts 26and 27. The shaft 32 carries the spur gear-wheels 34 and 35, the gear 34being in mesh with the gear 28 and being driven by said gear. Likewisethe shaft 33 carries the spur gear-wheels 36 and 37, the gear 36 beingin mesh with the gear 30 and driven by said gear.

38 denotes a shaft journaled in suitable bearings and located as shownand having fixed thereon intermediate its ends a drivepulley 39 and aiiy-wheel 40. This shaft 38 has also mounted thereon loose gear-wheels41, 42, 43, and 44, which are caused to rotate with said shaft at theproper time by means .of the clutches 45 and 46, which have a slidingconnection with the said shaft, but which rotate therewith and areshifted by means of the forked shifting levers 47 and 48 to alternatelyengage their respective loose gearwheels, which are each provided withclutch members, as shown, to throw the same into and out of operation,so that in the alternate lowering of the buckets of ore the drive-pulleymay be continually driven in the same dirotate in bearings located onthe frameworkl IOO IOS

rection, the inertia of the heavy fly-wheel serving to steady themovements of said pulley during the operation of shifting of theclutches, motion being imparted to the said drive-shaft 38 through thetrains of gearing before mentioned alternately by means of the shiftingclutches, the operation of which will be now more fully described.

Referring first to the right side of the machine, the bucket 8 havingbeen filled and on its downward movement will cause the wheel 16 and`the shaft l8 to rotate from right to left, driving the wheel 20 in thesame direction and causing the sprocket-chain 22 to move in thedirection of the arrows to drive the sprocket-pinion 24 on the shaft 26,and thereby drive the spur-gears 28 and 29 in the direction of the arrowindicated thereon. The gear 29 being in mesh with the spur-pinion 41will cause the same to turn in an opposite direction, as indicated bythe arrow placed thereon, said spur-pinion 41 through the clutch 45causing the shaft 38 to rotate, thereby driving the belt-wheel mountedthereon and causing the same to rotate in the direction of the arrow todrive the belt operating the crusher mechanism. Upon the descent of thebucket 9 after having been filled the shaft 18, wheels 16 and 20, andother mechanism just described will be caused to rotate in an oppositedirection. The clutch 45, however, has in the meantime been thrown intocontact with the spur-pinion 42 and away from the pinion 41, leavingsaid pinion 4l to turn idly upon the shaft 38. In order that thebelt-pulley 39 may be kept continually running in the same direction,thegear-wheels 34 and 35, mounted upon the counter-shaft 32, are interposedbetween the gear 28 and the pinion 42 to impart motion to said pinion,and thence through the clutch 45 and shaft 38 to the belt-pulley 39 torotate said pulley in the same direction it was traveling in the firstinstance, the inertia of the fly-wheel serving to keep up a steadymovement during the shifting of the clutch mechanism.

The operation of the left side of the device being exactly the same asthat just described, the description of one, it is thought, will besufficient for the other, it being understood, however, that themechanism of each side is complete in itself and distinct from theother,

' the two mechanisms being preferred for obvious reasons, principallythat power may be continually exerted to rotate the drive-pulley byalways having one full bucket on the downward movement.

If for any reason the crusher cannot use the ore as fast as broughtdown, waste rock, containing no ore, is sent down in the buckets anddumped to one side of the chutes leading to the mill until more ore isneeded.

Any suitable means (not shown) may be employed by the clutch-operator tonotify the car-operator at the proper moment to dump ore into the emptybuckets.

The speed of the operating machinery may be controlled and regulated byanysuitable brake mechanism.

It will of course be understood that various changes in t-he form,proportion, and the minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of this invention. a

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

1. In a weight-motor, the combination with the belt-pulley; of means fordriving the same, said means consisting of the alternatelyweightedbuckets attached to the' ends of sprocket-chains running over largesprocketwheels mounted upon shafts journaled at aA i higher level thansaid belt-pulley, smaller sprocket-wheels mounted upon and driven by thesaid shaft, endless chains or belts connecting said sprocket-wheels withthe sprocket-piuions located at approximately the level of thebelt-pulley and driving the same through the medium of the interposedtrains of gearing, substantially as and for the purpose set forth.

2. In a weight-motor, the combination with the belt-pulley mounted upona shaft journaled in bearings in aframework situated at a` lower levelthan the power employed in operating said pulley, means for transmittingsaid power to said pulley, the said means consisting of the endlesssprocket-chains driven by said power and driving sprocket-pinionsmounted on shafts journaled in bearings in the aforesaid framework, saidshafts having spur gears mounted thereon, loose gearwheels mounted uponthe aforesaid belt-pulley shaft, one of which being in mesh with one ofthe aforesaid spur gear-wheels and the other in mesh with a spur-gearmounted upon a counter-shaft also journaled in said framework and havingmounted thereon another gear-wheel which is in mesh with the other ofthe aforesaid spur-gears mounted upon the sprocket-pinion shaft, theclutch slidably but not rotatably mounted upon said belt-pulley shaft toalternately throw the aforesaid loose gear-wheels into and out ofoperation, thereby imparting acontinual motion to said belt-pulley inthe same direction from the alternate application of the prime motivepower by means of the interposed gearing, and a balance-wheel mountedupon said belt-,pulley shaft to impart a steady uninterrupted motionthereto during the shifting of the said clutch, substantially as and forthe purpose set forth.

vIn testimony whereof I have khereunto set my hand in presence of twosubscribing wit- HBSSGS.
